Problema Solution
A small airplane is flying at an elevation of 1057 meters when it begins a slow, steady descent. It descends at a rate of 101 meters per minute.
a. Write an equation that shows the elevation of the plane, h, after m, minutes of descent.
b. How many minutes will it take the airplane to reach an elevation of 148 meters?
Answer provided by our tutors
(a) The equation is h = 1057-101m
(b) h = 1057-101m = 148
We solve it, m = 9
So it takes 9 min to reach an elevation of 148 meters
